Description

Technical Field

[0001] This utility model belongs to the field of blind valve technology, and in particular relates to an electric explosion-proof blind valve. Background Technology

[0002] A blind valve is a gate valve that can be manually, electrically, or pneumatically / hydraulicly shut off gaseous media. It is generally classified into electric blind valves, hydraulic blind valves, pneumatic blind valves, closed gate valves, and electric open blind valves.

[0003] Currently available blind valves have the following problems when used:

[0004] 1. When using traditional blind valves, if the pipeline needs to flow a liquid with high viscosity, the liquid tends to stick to the surface of the blind valve. If the accumulation time is long, it can affect the flow of liquid inside the blind valve and make cleaning inconvenient.

[0005] 2. Traditional blind valves require a sealing ring to seal the valve during both opening and closing to prevent liquid from flowing out of the pipe. Over time, the sealing gasket may loosen and need to be replaced. Furthermore, the sealing ring is relatively large and difficult to install during replacement. Utility Model Content

[0006] The purpose of this utility model is to provide an electric explosion-proof blind valve to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: An electric explosion-proof blind flange valve includes a blind flange valve body, a movable plate is provided inside the blind flange valve body, a frame is sleeved on the outside of the movable plate, a scraper is fixedly connected to the side of the frame, two scrapers are provided, a fixing block is fixedly connected to the top of the movable plate, a locking block is fixedly connected to the side of the fixing block, the locking blocks are symmetrically distributed, a locking groove is opened inside the frame, and the locking blocks are embedded in the locking groove.

[0008] Preferably, a sealing gasket is embedded inside the movable plate, and an installation ring is sleeved on the outside of the sealing gasket. A square plate is fixedly connected to the side of the installation ring, and a rubber ring is embedded inside the square plate.

[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an electric explosion-proof blind valve.

[0028] like Figure 1-4 As shown, this utility model discloses an electric explosion-proof blind flange valve, comprising a blind flange valve body 1, a movable plate 2 inside the blind flange valve body 1, a frame 6 sleeved on the outside of the movable plate 2, scrapers 17 fixedly connected to the side of the frame 6, and two scrapers 17. A fixing block 7 is fixedly connected to the top of the movable plate 2, and a locking block 10 is fixedly connected to the side of the fixing block 7. The locking blocks 10 are symmetrically distributed. A slot 16 is opened inside the frame 6, and the locking blocks 10 are embedded in the slot 16. By adding a movable plate 2 inside the blind flange valve body 1, a frame 6 sleeved on the outside of the movable plate 2, and scrapers 17 installed on the side of the frame 6, this invention achieves its intended effect. 7. A fixing block 7 is installed on the top of the movable plate 2, and a locking block 10 is installed on the side of the fixing block 7. A slot 16 is opened inside the frame 6. When the blind valve has been used for a long time and a lot of sticky liquid adheres to its surface, it needs to be cleaned in time. At this time, simply move the movable plate 2 so that the movable plate 2 drives the scrapers 17 on both sides to move until the sticky substance is cleaned. After cleaning, the locking block 10 on the side of the fixing block 7 is embedded in the slot 16. At this time, the frame 6 can be fixed to prevent the frame 6 from sliding on the movable plate 2, making it easier to clean the movable plate 2.

[0029] A sealing gasket 4 is embedded inside the movable plate 2, and an installation ring 5 is sleeved on the outside of the sealing gasket 4. A square plate 18 is fixedly connected to the side of the installation ring 5. A rubber ring 19 is embedded inside the square plate 18. A fixing rod 12 is fixedly connected inside the movable plate 2. A ball head 13 is fixedly connected to one end of the fixing rod 12. The fixing rod 12 is inserted inside the square plate 18. By embedding the sealing gasket 4 inside the movable plate 2, sleeved on the outside of the sealing gasket 4, installing the square plate 18 on the side of the installation ring 5, and embedding the rubber ring 19 inside the square plate 18, and installing the fixing rod 12 inside the movable plate 2, a ball head 13 is installed at one end of the fixing rod 12, and the fixing rod 12 is inserted inside the square plate 18, when the sealing gasket 4 needs to be replaced after a long period of use, the installation ring 5 can be pulled down directly, and the new installation ring 5 and sealing gasket 4 can be installed on the movable plate 2. The movable rod and ball head 13 are then passed through the inside of the fixing plate, thus fixing the new sealing gasket 4, making the replacement of the sealing gasket 4 more convenient.

[0030] A handle 8 is fixedly connected to the top of the frame 6. The handle 8 is rectangular in shape. By installing the handle 8 on the top of the frame 6, the frame 6 can be moved easily by holding the handle 8.

[0031] A groove 3 is opened on the surface of the movable plate 2, and a slider 15 is fixedly connected to the side of the frame 6. The slider 15 is embedded in the slot 16. By opening a groove 3 on the surface of the movable plate 2 and fixing the slider 15 to the side of the frame 6, the slider 15 slides inside the groove 3 when the frame 6 is moved, preventing the frame 6 from falling off the movable plate 2.

[0032] The mounting ring 5 is fixedly connected to the side of the limiting block 14. The moving plate 2 has a limiting groove 11 on its surface. The limiting block 14 is embedded in the limiting groove 11. By installing the limiting block 14 on the side of the mounting ring 5 and the limiting groove 11 on the surface of the moving plate 2, the mounting ring 5 can be easily installed by snapping the limiting block 14 into the limiting groove 11.

[0033] The mounting ring 5 is fixedly connected to the handle 9. There are two handles 9. By holding the handle 9 on the surface of the mounting ring 5, the mounting ring 5 and the sealing gasket 4 can be directly removed.

[0034] The working principle of this electric explosion-proof blind flange valve is as follows: When using this electric explosion-proof blind flange valve, simply install it in the desired location, and it can be used immediately. Simply move the movable plate 2 to control the flow of liquid. When the valve has been used for a long time and a large amount of viscous liquid adheres to its surface, it needs to be cleaned promptly. To do this, simply hold the handle 8 and move the movable plate 2, causing it to move the scrapers 17 on both sides until the viscous substance is completely removed. When moving the frame 6, the slider 15 slides inside the groove 3 to prevent the frame 6 from falling off the movable plate 2. After completion, insert the locking block 10 on the side of the fixing block 7 into the slot 16. This will fix the frame 6 and prevent it from sliding on the moving plate 2, making it easier to clean the moving plate 2. When the sealing gasket 4 needs to be replaced after a long period of use, simply pull down the mounting ring 5 by holding the handle 9, install the new mounting ring 5 and the sealing gasket 4 on the moving plate 2, pass the moving rod and ball head 13 through the inside of the fixing plate, and snap the limiting block 14 into the limiting groove 11. This will fix the new sealing gasket 4, making it easier to replace the sealing gasket 4.
